指摘８れる。Since there are problems such as oxidation of the solid wire A bead surface and a decrease in the ease of embroidery, the common place is used as ilJM.On the other hand, the 7-wire wire does not have the above-mentioned drawbacks,
Shira also manufactures a wide variety of 9-year products by mixing flux.1!1. There is an advantage that the wires can be used differently depending on the type of base material, etc. However, these wires are sent into the conduit via a straightening roller and a selection roller, and the wires are energized at the welding tip portion and are connected to the base material. Welding is performed while generating an arc between the welds, but in order to perform stable welding and obtain high-quality weld metal, the wire must be fed at a constant rate. Oil and moisture such as lubricant attached to the wire surface must be completely removed in the final finishing stage, and heat treatment is essential.There are two heat treatment methods for wire: patch method and strand method. Patch type systems account for most of the raw flow;
In this method, wire rods are bundled into coils and put into a heating furnace and heated in an inert atmosphere for several hours to several tens of hours, but because the convection of inert gas is insufficient, There is a problem in that the flux changes locally depending on the degree of contact with the atmospheric gas.Therefore, especially in the case of a 7-lattice-cored wire, there is a problem in that the flux deteriorates locally. In addition, under the above escape conditions, an annealing effect is also applied, but since the temperature inside the furnace is not necessarily uniform, the annealing effect is uneven, resulting in uneven tensile strength. It has also been pointed out that due to the curling, the wire forms a single layer at the exit of the feed roller during welding.

The book @'JA8 and others focused on the above-mentioned complicated circumstances, and made flux-cored wires efficiently without creating a messy interlayer.
The present invention was completed as a result of such research and consists of a ferritic stainless steel hoop filled with 7 lux. When producing flux-cored wire f for stainless steel, the black-cored wire is drawn to the product diameter and then energized through a plurality of power supply rollers to heat the wire at 500 to 750°C while passing between the electrodes. The gist lies in heating the flux-cored wire by holding it for 0.08 to 0 seconds and heating it with electricity.In the present invention, the flux-cored wire is heated using the regular iron heating method, which is a heating method in which the wire is While running in the direction of the wire, it is brought into contact with a power supply roller and heated by electricity, and the heat generated inside the wire can be used to raise the temperature at home, and it heats up continuously in a very short period of time, only a few seconds. Since the wire is heated evenly while traveling in the axial direction, there is no bending during local heating, and high quality product wire can be obtained. can.

Targeting flux-cored wire using 47-pu,
When we investigated the feed resistance during gas V-rudo arc welding, it was found to be inferior to II. It is approximately 3.0148 degrees under the above conditions, and it is recommended to set the wire strength based on this.
The relationship between the tensile strength and buckling strength of flux-cored wire is as shown in Figure jI6, and the wire tensile strength is 45
It can be seen that when the welding wire becomes less than ky/am2, the Wi bending strength of the welding wire falls below the maximum resistance (approximately LOk@ of e above), causing buckling, etc., resulting in failure of feeding and formation of islands.Furthermore, Fig. 7 is an experimental graph showing the effect of heating holding time on wire tensile strength at each energization time, and heat treatment a
As the WL increases, the tensile strength rapidly decreases even if held for a short period of time, so the quantity key 1 becomes 1 female. Therefore 451w/-
In order to stably obtain a tensile strength of m2 or more, the wire heating process must be set to 760° C. or less and the heat retention time must be set to LO seconds or less.

る。That is, the heat pattern during electrical heating in the present invention is not particularly limited as described above, but from the viewpoint of tensile strength related to the buckling strength of the wire, the upper limits of the heat retention temperature and heat retention time are 750°C and 2.0°C, respectively. On the other hand, the lower limits of heat retention time and heat retention time are limited to 500° C. and 0.08 seconds, respectively, due to the amount of hydrogen directly linked to welding defects. In other words, 1
By setting the instant heating conditions within the above preferred a'lA degree and time, it is possible to stably obtain high quality ferritic stainless steel vXH flux-cored wire with high productivity.

表面に突出した形で形成されると。It is desirable to take countermeasures that take into account problems such as downward twisting.In other words, since 7-lux wire has seams as shown in figure s2, twisting is likely to occur during the wire drawing process, and solid wire In addition, cleaning is sometimes performed to roughly remove lubricants, etc. prior to heat treatment, but it is not possible to sufficiently remove the ffi agent that has entered the joints of the hoop. At the stage of increasing the length of the energized heating pipe, conductive thick lubricants and the like adhere to and accumulate on the energizer. Then, the contact between the power supply roller and the wire becomes poor, causing sparks and spark defects on the wire surface.
Sometimes it even leads to disconnection. When this spark flaw is formed in a protruding shape on the wire surface.

By increasing the lubricant removal member in the straightening device 2, the lubricant removal member is thoroughly removed at the wire joint, thereby suppressing energization failures. Further, as means 112, the wire runout during high-flow operation is prevented by idle rollers d, e, and f in the four-electric heating furnace, thereby preventing energization failures caused by wire runout. Furthermore, as a third means.

Contact stability is achieved by adjusting the fence so that Pl>P2 for Pl>P2, and quickly burning off the lubricant on the wire surface that prevents the 4111 property between the power supply rollers C and improving the familiarity between the power supply roller B and the wire W. In other words, in the energization heating process, the electric current fi1 is the electric current in the direction of the feed roller b at the feed roller b! . Since the current flowing through the power supply roller B is divided into the current il in the direction of the power supply roller C, the current flowing through the power supply roller B is the largest, and sparks are most likely to occur in the row 96 portion. If it is possible to suppress the sparks in the entire electric heating system (a), then the sparks in the entire electric heating system can be substantially eliminated.In this way, in the present invention, the above three spark prevention measures and y
